Relationship among otoacoustic emission suppression and auditory processing measures in adults

The purpose of this Capstone Project is to help determine whether performing otoacoustic emissions with contralateral noise may be used in the diagnosis of Auditory Processing Disorder.

Auditory and audio-visual reception of words in noise by observers with normal and impaired hearing

This dissertation examines auditory perception and audio-visual reception in noise for both hearing-impaired and normal hearing persons, with a goal of determining some of the noise conditions under which amplified acoustic cues for speech can be beneficial to hearing-impaired persons.

The discrimination of auditory and visual number

This study compares the discrimination of successive visual number and successive auditory number using the same stimulus durations and presentation rates for both stimuli. The accuracy of the discrimination of successive number decreased as the presentation rate increased and the number in a series increased.

Auditory brainstem response with alternative transducers: implications for newborn hearing screening

This paper studies the efficacy of a bone-conducted transducer compared to a traditional air conduction transducer for auditory brainstem response screening of newborns.

Visual perceptual skills, reading ability and the young deaf child

This paper is a review of a study investigating the relationship between visual perceptual skills and reading abilities of young deaf children.

The effects of extracorporeal membrane oxygenation (ECMO) on auditory brainstem responses (ABR) in neonates

This paper presents a study of the effects of extracorporeal membrane oxygenation (ECMO) on the auditory brainstem response (ABR) of twenty-three neonates, and whether there was asymmetric ABRs in the neonates who had ECMO.

Cross-modality temporal resolution for auditory, vibrotactile, and visual stimuli

This paper reviews a study of cross-modalities and within-modalities and their effects on speech perception.

Reanalysis of perceptual confusion matrices

This paper presents a study reformatting and reanalyzing data collected in a 1955 study of the perception of sixteen different consonants in consonant-vowel combinations, by human listeners.

Perceptual validation of an acoustic metric for measuring vowel production by deaf children

This paper discusses a study to validate the metric developed in the Geers and Moog Cochlear Implant Study at CID to measure the speech production of hearing impaired children.

The slow cortical evoked potential: cross modality interaction of auditory, vibro-tactile and shock stimuli

This paper discusses a study that collected cortical evoked responses when stimuli of different modalities were presented.

Auditory difference limen for duration in deaf and hearing listeners

This paper reviews a study to determine if deaf children can discriminate fine durational changes in acoustic signals or whether the impairment of the peripheral auditory system interferes with the temporal precision necessary for such tasks.

Most comfortable listening levels of hearing impaired people: effects of everyday auditory and visual environments

This paper discusses a study to evaluate the changes that may occur in most comfortable listening levels when hearing aid users encounter a realistic auditory and visual environment.

Are there hazardous auditory effects of high-frequency turbines and ultrasonic dental scalers on dental professionals?

The purpose of this pilot study was to survey dentists in the St. Louis area to assess their subjective opinion of commonly used dental handpieces as well as history of noise exposure and use of hearing protection. Selected handpieces were then chosen to measure their output levels and determine if emissions are hazardous to the auditory system.

Comparing auditory steady-state response and auditory brainstem response in normal hearing adults

This paper compares the auditory steady state response (ASSR) thresholds with the click-evoked and tone burst auditory brainstem response (ABR) thresholds in their ability to predict known behavioral thresholds in normal-hearing adults.
